Abstract

The utility model relates to an interaction socket ball lock device. Ball setting holes 11 are arranged on the lock head 1 and the lock core 3 of the utility model, and a round outer ball 9 and a round inner ball 6 are arranged in the ball setting holes 11, wherein, the round inner ball 6 is a hollow cylinder, an inner socket ball 7 is arranged in the round inner ball 6, the round outer ball 9 is a hollow cylinder, and an outer socket ball 8 is arranged in the round outer ball 9. At least one interaction ball setting hole 22 is arranged on the lock core 3, an interaction spring ball 17 and a pressure spring or the interaction ball 18 are installed in the interaction ball setting hole 22, a column nail hole and a movable column nail 16 are arranged in the position corresponding to the interaction ball setting hole 22 on the lock key 4 of the utility model. The number of rows for setting balls of the lock device is increased to two times as compared with an ordinary lock device, so the number of balls is increased, and the theft protection performance is improved by the interaction balls.

Description

Interactive socket ball lock device

The utility model relates to commodity, belongs to the metal latch class.

Existing metal tapered end, interior cover lock core, bore the hole of bead of putting of some perforations at the side of tapered end and lock core, in putting the hole of bead, put into two balls, one is placed on tapered end one side, another grain is placed on lock core one side, ball and spring is stayed put the hole of bead putting into spring by the outer end of tapered end and seal up mounting again.When key being inserted the key hole of lock core, key will respectively be put in the hole of bead ball by lock core one side and eject and fill and lead up lock core just, make that lock core also can rotate when twisting key, drive lock body tail bar, and lock is opened.By adjusting the length combination of ball, can stipulate that every lock needs different keys.But because the length and the limited amount of ball, the quantity of this combination (row's of being commonly called as number of codes) can not be too many, and identical possibility is bigger, and theftproof performance is relatively poor.

The purpose of this utility model is the metal latch of a kind of safety and reliability of design, increases row's number of codes by the quantity that increases ball, thereby improves the theftproof performance of lock.

Structure of the present utility model also is to be made of tapered end and lock core two parts, bore the hole of bead of putting of several perforations at the side of tapered end and lock core, in putting the hole of bead, put into two balls, we are referred to as outer ball by the ball of tapered end one side, we are referred to as interior ball by lock core one side ball, outer ball and interior ball are designed to hollow ball, suit overcoat pearl in the ball outside, in interior ball, overlap pearl in the suit, so just make that putting pearl row number doubles, choosing 1 to 2 in addition puts the hole of bead and increases the design of the interactive pearl of button, its way is to open an interaction at the opposite side of lock core facing to the position of putting the hole of bead to put the hole of bead, and interactive pearl is installed in the hole of bead is put in interaction, and interactive pearl promotes the opposite and puts interior ball in the hole of bead by being arranged on post nail on the key, length by the adjustable column nail implements to put sign indicating number, and the difficulty of forging key is increased greatly.

The utility model is owing to used interior cover pearl design, and the length of well-designed ball and cover pearl can the row's of making number of codes increase greatly, adds that interactive pearl design makes theftproof performance improve greatly.

The example of contrast accompanying drawing is further described the utility model below:

Accompanying drawing is a section of structure of the present utility model.

Lock core 3 is installed in the tapered end 1 and is used snap ring 2 chuckings, one mortise lock spoon passage 20 is arranged in the lock core 3, one end of key passage 20 inserts lock body tail bar 5, the other end is used for inserting key 4, open several in a side of tapered end 1 and lock core 3 and put the hole of bead 11, put in the hole of bead 11 and be sidelong into interior ball 6 by lock core one, interior ball 6 is a hollow cylinder, put intragranular cover pearl 7 in the interior ball 6, put in the hole of bead 11 and be sidelong into outer ball 9 by tapered end 1 one, outer ball 9 is a hollow cylinder, lays an overcoat pearl 8 and a cover pearl spring 10 in the outer ball 9, put outside the 11 inside and outside balls 9 of the hole of bead and adorn an outer pearl spring 12, secure with envelope pearl 13 in the end of putting the hole of bead 11.

This example also arranges 1 to put the hole of bead interactive pearl is installed, flat pearl 15 in this puts the hole of bead, installing by a side of lock core 3, install by a side of tapered end outer flat pearl 14 and outside pearl spring 12, secure with sealing pearl 13 in the end of putting the hole of bead at last.Put on the opposite lock core in the hole of bead at this, have an interaction and put the hole of bead 22, interaction is put interactive hoodle 17 and interactive pearl stage clip 18 is installed in the hole of bead 22, and with mounting 19 hole of bead 22 is put in interaction and seal, the elastic force of interactive pearl stage clip 18 is bigger than the elastic force of outer pearl spring 12, and the position that the hole of bead 22 is put in corresponding interaction on key 4 is opened post nail hole and a movable post nail 16 is installed.

Owing to adopted interior cover pearl, the tooth number of key 4 increases greatly than common key, the tooth form of key is designed to taper shape or sphere, when key 4 is inserted key passage 20, if the key tooth can be with the sideline of whole interior balls 6 and the flat lock core 3 of interior cover Zhu7Ding, and post nail 16 also can be with the sideline of the flat lock core 3 of interior flat Zhu15Ding, and then at this moment rotating key 4 just can rotational lock core 3, thereby can rotational lock tail bar 5, realize unblanking.
